Design is on the food packaging bags with printing? Can contaminate food?

“ Yen & throughout; , the food and clothing live line account for a large part of our daily expenses. In a supermarket store, all kinds of food packing bag to let a person too many things to see. Bags in addition to the labeling on the date of production, ingredients such as the regulations of the state of origin of the information, to a large extent is the important tool of business marketing. A fine food sack tend to attract more customers to buy. So how these exquisite pattern is printed? But these patterns are printed ink, so the remaining problems exist. Food packaging material surface printing ink by pigment, linking agent, solvent, auxiliary agent. The organic solvent and heavy metals to human body harm is serious. In gravure printing ink solvent used in general have butanone, xylene, toluene, butyl alcohol, etc. Especially the butanone, residual smell is very thick. These solvents, although by drying can remove most, but the residual solvents are migrated to food the harm to human body. The residual solvent was taken to a composite process, the more difficult to run away, after composite migrate slowly permeate, so must be solvent residue control to a minimum. In order to avoid and solve problems exist benzene soluble ink, green ink arises at the historic moment, and began to be widely used. Why is named environmental printing ink? That's because the range of ink in the process of production, the use will not damage to the environment, also won't produce physical harm to the use of personnel, more pollution, won't make food sack of food received. Now, widely used in domestic environmental protection series ink generally have three kinds: 1. Water-based ink, water-based ink, 水- - - - - - 基于墨水) Mainly by water soluble resin, organic pigments, solvents and related auxiliary by the composite grinding processing. Water-based ink is the vast majority of flexo packaging printing house at home and abroad with ink. Water-based ink does not contain volatile organic solvents, not only can reduce the printing quality of residual toxicity, and can prevent fire by static contact with flammable solvents. 2. Uv ( UV） Curing ink solidification process of the uv curing ink is a photochemical reaction process, namely in under the action of uv energy, prepolymer curing film in a very short time, in addition to causing the surface of the ink curing, ultraviolet ray can permeate into liquid in the uv curing ink, deep and stimulate further curing ink film. Compared with traditional ink, uv curing ink polymerization dry more thoroughly, no any pollution or solvent evaporation, ink film curing of 100%. 3. Electron beam curing ink ( EB ink) Electron beam curing ink is refers to under the irradiation of high energy electron beam can quickly shift from liquid to solid ink, also known as EB ink. Electron beam curing ink is mainly composed of pigment, links, auxiliary agent, pigment, etc. Electron beam curing by using electron beam irradiation energy, radiation chemical reaction with active liquid chemical formula, rapid drying curing at room temperature. In professional food packaging industry, low migration inks printing is an important research topic, continuously improve the printing process, the greatest degree to reduce ink migration degree is the assurance of food safety packaging printing. Believe in the future as the country attaches great importance to and people life quality rise ceaselessly, environmental printing ink will be more and more widely used.
